Sorry guys, it's the one piece rotors on there now, although I would buy 2 piece rotors at this point. I don't care. I just don't want to have to throw away my BBK just because Rotora decided in their infinite wisdom to not offer an alternative for older models like mine.

I will take any rotors that will work at this point. They're not falling apart or anything. I still drive the car, but I can feel they're starting to warp and to be honest I can't complain about that since I've never turned them since I got them eons ago. Thing is that since they're slotted and drilled and now worn, nobody is going to attempt to turn them. Not worth the headache at this point to do that, so I'm searching for just replacing the rotors since the calipers eventhough they're not the latest and greatest of course are still working perfectly.

You'll just have to measure the following:
hat height
rotor thickness
rotor diameter
The hub opening is 62mm. Then you'll have to contact other manufacturers and see if they have a similar rotor in 5x114. Contact Futura, Brembo, Wilwood, etc...
